Problem is, the fees are going to be SO EXCESSIVE... it may not even be worth it for you to press forward.i would recommend the conventional route if that's an option. 

Say you have been supporting yourself on $3k a month for the last year or two, you will be very hard pressed to go down to $2.5k a month, if you don't believe me, then try it.You're reply comes off as defensive. 

I would bet money that the most popular cabins have the easiest access to GSP and have all the "amenities" like high-speed internet and cable/satellite tv, things that most "outdoorsy" people don't care all that much about since they're going to be standing in a river casting for trout all day.

Shut off internet and TV.

For locations that need 3 prongs like fridge, tv, etc I will replace them with GFCI and connect to a local ground source like a pipe as you suggest.

You'll get caught on the fall too in equities and be pressed for margin.

One in my market has as one of the GPs one of the primaries (the RE agent) from a tv show on finding luxury properties.  

My idea is turn it in a 4/3 converting the basement into a conforming bedroom with window and closet and a tv room/living room and the laundry into a bathroom and put the washer and dryer in the garage.

Sometimes owners will be completely unrealistic so just say "have a nice day" and press the next button

I was just opening the dialogue and pressing for a bit more context.
